Cask Ale Week: the Format Nobody Else Can Pour

Cask Ale Week runs from 17 to 27 September, and it celebrates the one thing British beer cannot ship abroad: unfiltered, unpasteurised beer that finishes fermenting in the cellar of the pub you drink it in. The publican is part of the recipe, which is why nobody else has copied it, and why a bad one tastes like an apology.

Thirteen pints worth chasing this week, what the plaque on the door actually promises, and the numbers behind a revival that is being led, of all people, by drinkers in their twenties.

The misconception we keep apologising for

Anywhere else in the world, you would read warm and flat on a back-of-bottle review and put the glass down. In Britain, that combination — given a working cellar and a publican who knows what they are doing — is the format. Cask ale is not a fault. It is unfiltered, unpasteurised beer that finishes its fermentation inside the cask, in the pub cellar, under the publican's care. It is poured at cellar temperature, around 11 to 13 degrees, which is cool to the touch but not cold to the tongue. Its carbonation comes from secondary fermentation and a soft natural release, not a CO2 cylinder.

This is what makes cask hard to copy. A keg lager travels. A bottle of Bordeaux travels. A cask of bitter, properly kept, is a living thing that exists for a few days in one specific cellar, on one specific bar, in one specific pub. It cannot be exported as a product. It can only be drunk in place. The technical window is small — Des de Moor's recent book on cask puts the ideal serving window at three days once broached, four with very careful cellar work — but the cultural consequence is huge. That makes it the most local format the global drinks industry has, and the easiest to lose, which is why the people who care about it care so loudly.

Who is actually drinking it

This is the biggest one yet: more than 10,000 pubs have signed up, with hundreds of breweries, a million free tasters between them, and an app trail that pays out in a T-shirt after twelve pints. The organisers are making a point with the number, because the trade needs the encouragement.

The audience is changing underneath it. CGA’s June figures put 16% of cask drinkers between 18 and 34, and the Society of Independent Brewers reports a quarter of 18 to 24-year-olds have now tried cask, up ten per cent on the year, with some independents seeing cask growth in double digits.

Firebrand Brewing in Cornwall is one of them, at 18% up on the year. Its founder Joe Thomson told The Drinks Business that drinkers "seem to be embracing cask in a way we've not seen for years", and marked the week by brewing a 4.8% pale ale from an 1864 recipe: pale malt, Goldings, nothing else. The reasons younger drinkers give are not the ones the trade expected either. Most cask is under 4.5%, it cannot be delivered to your door, and it is the cheapest proper pint on the bar: £4.54 against £4.97 for the average pint.

None of which means the category is fixed. Cask still sells 8.1% of draught beer by volume and only 7.4% by value, volumes are falling where distribution has been cut, and a week of celebration does not reverse a decade. The cheapness is the sore point in the trade. St Austell's chief operating officer Andrew Turner put it plainly to the Morning Advertiser in July: cask is "the most difficult beer to look after, requires the most energy, the most effort, but yet it appears to be the cheapest pint on the bar — and the two just don't go hand in hand." He expects it to be the trendiest drink on the bar again; he would rather it arrived with a price that paid for the cellar work.

What the plaque on the door promises

Cask Ale Week was started in the early 2000s by the Cask Marque Trust, the body behind the plaques and window stickers you have been walking past for years, and it runs with CAMRA and most of the trade behind it. Any pub can take part, Cask Marque member or not; the campaign names a Beer of the Day and a Brewery of the Day, and lists what is on near you.

For nearly thirty years, the Cask Marque Trust has been doing the quiet work of independently assessing British pub cellars: twice-yearly, by trained beer professionals, with a star rating that publicans actually compete on. The plaque on the door, the sticker in the window, the listing in the CaskFinder app — all from the same accreditation pipeline.

The trust's beer-quality accreditation — what used to be Beer Marque — has had its consumer-facing rebrand. It is now the Perfect Pint Promise, with a single line at the top of the page that should have been there years ago: your guarantee of a quality pint every time. Not a brewery marketing badge. Not a sponsorship deal. An independent standard you can trust. And it isn't a cask-only badge — PPP tests all draught: cask, keg, lager, stout, cider, no/low.

The point of the rebrand is what it says out loud. Beer Marque told you a pub had passed an inspection. Perfect Pint Promise tells you what the inspection is for: that the next pint you pull out a chair for is going to be in good nick. That is a much easier sentence to hear in a busy bar.

The infrastructure scales with the ambition. The Cask Marque Trust audits 7,000 5-star cellars right now; the Perfect Pint Promise aims for 3,000 fully accredited venues inside twelve months. The standard hardens at the same time — Beer Pro e-learning for bar staff, proper pour, correct glassware. The point isn't just the cellar any more. It is the whole pub.

The plaque is the same. The CaskFinder app is the same. The decades of cellar audits behind it are the same. What changed is the language at the front of the bar, and it is sharper.

CAMRA, real ale, and a community that did the work

None of this would still exist without CAMRA. The Campaign for Real Ale was founded in 1971 by four men in a Kerry pub who thought British brewing was being homogenised into oblivion. They were right. Most of British brewing in the 1970s was being homogenised into oblivion. Cask survived because a consumer organisation argued for it, year after year, in front of policy makers, brewers, MPs and drinkers who had been told their preferred format was over.

The Good Beer Guide is CAMRA's. Local beer festivals are CAMRA's. The annual Pub of the Year network is CAMRA's. Decades of work on pub protections — on planning consent, on the tied-pub Statutory Code, on the small brewers' duty relief, on stopping the conversion of pubs into supermarkets — is CAMRA's. So is the community that turns up to drink the beer.

That community is the actual moat. Cask ale is the most consumer-defended product in British drink. Other categories have lobby groups; cask has a membership. 150,000 paid-up members carrying around a guidebook and an opinion is a different kind of asset to a marketing budget.

Thirteen pints for the week

Not the thirteen best cask ales in Britain. Nobody could agree that list, and half of it would be a beer brewed eight miles from your house in numbers too small to find. These are the ones you can actually walk in and order: widely distributed, kept by pubs that know them, and between them covering most of the country. A pub with any of these on the bar is a pub that has bothered.

The better pint this week is probably the local you have never heard of, poured by someone who cares. Ask what is going well. These thirteen are what to do when nobody offers.

Thirteen to look for

  1. Fuller's London Pride — now under Asahi, but still carrying one of English cask's most recognisable badges. The London bitter against which all other London bitters are measured. Bready, biscuity, brilliantly drinkable. Hammersmith via every freehouse south of the Thames.
  2. Timothy Taylor's Landlord — Keighley. The pint that converts lager drinkers back. Four times Champion Beer of Britain, and now the biggest seller in cask.
  3. Greene King Abbot Ale — Bury St Edmunds. At 5% the strong end of a session, and one of the most widely poured cask ales in the country, which is its own kind of achievement. Fruitcake and bitterness, everywhere from village locals to city chains.
  4. Draught Bass — the Burton one. Now contract-brewed for AB InBev's Budweiser UK at Carlsberg's Marston's site in Burton, but kept alive by a drinker network that maps every pump in the country. The pump count tripled this year, from 350 outlets to over a thousand. Cask Drinker Network. National Bass Day. The hand-pulls are coming back.
  5. Harvey's Sussex Best — Lewes. The proof that a small regional brewer with a single town's worth of conviction can produce one of the great session pints. Bitter that tastes like the South Downs.
  6. Boddingtons (cask) — Manchester, via J.W. Lees. Relaunched as cask in 2025 — 150 Greater Manchester outlets first, 400 nationally by January 2026, now 15% of Lees's total production. The Whippet in EC2 is one of London's. Cask only. The keg widget version isn't this beer.
  7. Adnams Ghost Ship — Southwold. Pale, citrus-hopped, modern enough to win the under-thirties without losing the cask faithful. Suffolk's quiet diplomat.
  8. Thornbridge Jaipur — Bakewell. Often called Britain’s first craft IPA, and 5.9% of proof that the argument between cask and craft was always a false one: it is at its best pulled through a handpump. Twenty-one years old this year, and still the one people remember.
  9. Theakston Old Peculier — Masham. North Yorkshire's strong dark ale, fifth-generation family-brewed, never not on form. The one for a cold night. If the pub has XB as well — 4.5%, ruby, first brewed in 1982 and named after the letters chalked on the cask — order that instead.
  10. Hook Norton Hooky Bitter — Oxfordshire. Brewed in a Victorian tower brewery that still uses steam. Perennial Cask Marque favourite. The pint you forget about until it is in front of you.
  11. Brakspear Bitter — Henley-on-Thames originally, now brewed at Wychwood in Witney. Bone-dry, double-drop fermented, faintly orange-peel. One of the oldest classic English bitter recipes still on a working hand pump. Dry enough to keep you on it all evening.
  12. Marston's Pedigree — Burton. The Burton Union system kept it alive for decades; the system is gone now but the beer endures. Pedigree by name and nature.
  13. Adnams Broadside — Southwold's other one. Strong, malty and Trafalgar-named: Ghost Ship's older brother.

Thirteen is an arbitrary number. Four more that would have done the same job: Butcombe Original, Oakham Citra, Titanic Plum Porter, Caledonian Deuchars IPA — the last of which is Edinburgh’s, and a reminder that cask did not stop at the border.

Why nobody else has this

Look down the list. Every one of them is from a region. None began life as a multinational product-board exercise. Every one is rooted in a region, a brewery town, a pub network, or a drinker memory that still means something. Several are still owned by the families or regional breweries that made them; others now sit inside larger corporate portfolios, where the commercial logic is increasingly clear: do not mess with the thing drinkers came back for.

That is the moat. No other country has a network of this size. Ireland keeps cask alive too, and Northern Ireland is on the Cask Ale Week map; nowhere else has thousands of pubs running it as the house format. The closest analogues — Belgian Trappist abbey ales, German Rauchbier in Bamberg, Czech tank lager in Prague — are formats that travel through bottles or kegs. Cask travels only into the cellar of the pub down the road. It is a deeply, irreducibly local thing, and Britain is the country that built a national network of pubs willing to run it.

Three ways to be old, three ways to claim heritage. Belgium have the oldest brewers — Rochefort has been brewing continuously since 1595, with abbey lineage back to 1230. Germany has the oldest breweries — Weihenstephan dates itself to 1040, and Munich’s oldest, Augustiner, to 1328. England have the oldest format. Only one of those three definitions of old can be poured, kept and drunk locally without first being shipped, filtered or pasteurised.

The big brewers have noticed

There is another reason this suddenly feels current. Heritage cask is no longer just something CAMRA members defend and regional brewers quietly keep alive. The big brewers have noticed the ghosts on the pub wall are worth money. It has the faintly familiar feel of craft beer a decade ago: once the independents proved the appetite was real, the larger players moved in for the brands, the credibility and the route to market.

Damm, best known in Britain for Estrella, has bought the Old Speckled Hen family from Greene King. JW Lees has brought Boddingtons back on cask. Allsopp's and Double Diamond are being revived. Draught Bass is on more than a thousand hand pumps again. Timothy Taylor's Landlord has overtaken Doom Bar at the top of the cask pile — Morning Advertiser's 2026 Drinks List puts Landlord ahead on both volume and value.

That is flattering, and slightly dangerous. It proves the category has cultural pull again. It also means cask is being rediscovered not only as beer, but as heritage IP: names, mirrors, pump clips, memories, and pub-wall ghosts that can be reactivated once the market is ready.

The handpull is fashionable again. The awkward bit is who owns the badge above it.

Where to drink it this week

Most of the thirteen travel into London freehouses; the rest are easy to find in their home regions. PINtPOINT lists the pubs serving each one, so the simplest way to organise an evening is to pick a beer and let the venue list do the rest. The harder pints are honest about themselves: Boddingtons in genuine cask is rare, and the Whippet in EC2 is one of the few places in London that has it.

If you want to do it properly, pick a Perfect Pint Promise pub — same Cask Marque Trust accreditation, plainer language on the door: that the pint you order will be in good nick.

Eleven days

None of this makes a badly kept pint taste better. It does mean that when you find a good one this week, someone in a cellar earned it.

Cask Ale Week runs to 27 September. The cellars are ready.

FAQ

What is cask ale?

Cask ale — also called real ale — is unfiltered, unpasteurised beer served from a hand pump or by gravity. Conditioning finishes inside the cask in the pub cellar, which makes the publican as important as the brewer. It is poured cool rather than cold and carries softer, natural carbonation. There is nothing wrong with the beer; it is meant to be like that.

Is Cask Marque the same as the Perfect Pint Promise?

The Cask Marque Trust runs the Perfect Pint Promise. It is the trust's beer-quality accreditation, formerly called Beer Marque, renamed to make the consumer guarantee clearer. The trust has been assessing pub draught quality for almost thirty years; the plaque, the CaskFinder app and the audits are the same lineage. The Perfect Pint Promise covers all draught — cask, keg, lager, stout, cider, no/low — not cask alone.

Is cask ale really warm and flat?

Cellar temperature, not warm. Lightly carbonated by secondary fermentation, not flat. Served as the brewer intended. The descriptors are anywhere-else fault sheets; in Britain they are a category.
